Applications

Usage examples

Freezer truck trailer
AKF301 receives power supply from truck +24V , then it is charging it’s external battery and supplying power voltage from truck battery to FM device.
When freezer is detached from truck, AKF301 is supplying power from freezer +12V battery to FM device. Additional external battery is not charged.

Regular or Platform truck trailer
AKF301 receives power supply from truck +24V , then it is charging it’s external battery and supplying power voltage from truck battery to FM device.
When trailer is detached from truck, AKF301 is supplying power from it’s additional external battery.
